Today’s performers also demonstrate how our notions have continued to evolve when it comes to Strauss’s subtle art of instrumentation and the undimmed modernity of his harmonic language. At Orfeo, Andris Nelsons and the City of Birmingham Symphony Orchestra are currently charting the virtuoso path taken by the young Strauss in his symphonic poems, when he shifted from the realm of the Brahmsians to the world of the Wagnerites. This was a path that found its goal in works such as Also sprach Zarathustra and An Alpine Symphony. And all the while, Strauss was establishing a reputation as the leading German music dramatist of the early 20th century. The fact that he retained his preeminent position among opera composers was especially thanks to the generation of conductors between Böhm and Nelsons. There was Carlos Kleiber with his legendary Rosenkavalier, as well as Joseph Keilberth and Rudolf Kempe, who did not restrict themselves to the major works of the canon but also conducted the lesser-known operas such as Feuersnot, Intermezzo and Die ägyptische Helena. Then there was Wolfgang Sawallisch, who conducted all of Strauss’s operas in Munich and even recorded a rarity for Orfeo – the seldom-played Sonatina for Winds in E flat. Alongside all these great conducting names – and without wishing to ignore the importance of his baritone and bass roles – we cannot here fail to mention the sopranos and mezzos without whom Strauss’s operas and songs would be unimaginable, and of whom we can list but a few here: Lisa Della Casa, Elisabeth Schwarzkopf, Leonie Rysanek, Lucia Popp, Christa Ludwig, Brigitte Fassbaender, Edita Gruberova, Anne Schwanewilms and Adrianne Pieczonka.
